PharmaACE Graduate Engineer Interview Questions and Answers

UPLC stands for Ultra Performance Liquid Chromatography.

• UPLC is a technique used in analytical chemistry to separate, identify, and quantify components in a mixture.

• It is an advanced form of liquid chromatography that utilizes smaller particle sizes and higher pressures for faster and more efficient separations.

• UPLC is commonly used in pharmaceutical, environmental, and food analysis.

• It offers improved resolution, sens...read more

Condensers are devices used to condense a substance from its gaseous to its liquid state.

• There are two main types of condensers: air-cooled and water-cooled.

• Air-cooled condensers use air as the cooling medium, while water-cooled condensers use water.

• Examples of air-cooled condensers include car radiators and air conditioning units.

• Examples of water-cooled condensers include cooling towers and refrigeration systems.

• Othe...read more

Azeotropic distillation is a process used to separate azeotropes, which are mixtures of liquids that boil at a constant temperature.

• Azeotropic distillation involves adding a third component to the mixture to break the azeotrope.

• The third component forms a new azeotrope with one of the original components, which can then be separated from the other component.

• This process is commonly used in the production of ethanol, wh...read more

Reynolds number is a dimensionless quantity used to predict fluid flow patterns and turbulence.

• Reynolds number is calculated as the ratio of inertial forces to viscous forces in a fluid.

• It is used to determine whether a fluid flow is laminar or turbulent.

• The range of Reynolds number for laminar flow is less than 2300, while for turbulent flow it is greater than 4000.

• In between these values, the flow may be transitional...read more
